The compact M600V Scout Light produces 150 lumens of brilliant white light or 120 mill watts of invisible infrared output for use with night vision devices-with no need for IR filters or spare lamps, attaches to Picatinny rail with a thumbscrew clamp. Simply twist the self-locking selector ring on the dual-spectrum V-series head to switch between output modes. In either mode, the M600V's TIR lens produces a tight beam suited for short- to medium-range applications. The high-efficiency LEDs are virtually immune to failure since there's no filament to burn out or break. Comes with a momentary/constant-on pushbutton tail cap switch and a momentary-on pressure-activated tape switch with a 7" cable that can be positioned where you choose. Also available are optional dual SR pushbutton/pressure pad switches. The M600V clamps solidly to any long gun equipped with a Picatinny rail via its integral Thumbscrew clamp. Constructed of high-strength aerospace aluminum with Mil-Spec hard anodizing for superior toughness and corrosion resistance and optically coated tempered glass for durability and maximum light transmission, the M600V is O-ring sealed to keep out dust, dirt and moisture. Battle-proven and built to withstand the rigors of combat.
